If you live in Terrace, Kitimat, or surrounding areas, you’ve probably asked yourself: Can a heat pump really keep my home warm when it’s -30°C outside?
It’s a fair question. For years, heat pumps had a reputation for struggling in cold weather. But technology has come a long way, and today’s cold-climate heat pumps are engineered specifically for Canadian winters. At Village Mechanical, we’ve seen them keep homes comfortable during the coldest weeks of January. Let’s bust a few myths and share what’s really possible in Northwest BC.
Myth #1: Heat Pumps Stop Working Below Freezing
This myth comes from older heat pump models that were never designed for harsh northern climates. Homeowners in the past often found themselves relying on backup heat once the temperature dropped.
Today’s cold-climate heat pumps—including Moovair Heat+, and Midea Xtreme Heat models—are built with advanced variable-speed compressors, smart defrost cycles, and updated refrigerants. These innovations allow them to maintain efficient heating down to -25°C and even -30°C.
In fact, cold-climate heat pumps in Canada are tested to meet performance standards in extreme northern conditions.
Myth #2: Heat Pumps Can’t Keep Up With Larger Homes
Another common concern is that heat pumps can’t deliver enough heat in spacious or older homes. The truth is, with the right design, they can.
The key is a proper heat-loss calculation (CSA F280 standard) that ensures your system is sized accurately. A one-size-fits-all approach won’t cut it. Ducted systems can distribute heat evenly throughout larger homes, while ductless mini or multi-splits are perfect for targeted comfort in specific rooms.
At Village Mechanical, we take a house-as-a-system approach, which means we don’t just install a unit—we adapt ductwork, improve airflow, and ensure your home’s comfort levels are balanced from top to bottom.
Myth #3: Heat Pumps Freeze Up in Northern Winters
Yes, outdoor units are exposed to snow and ice—but they’re designed to handle it. Cold-climate heat pumps automatically cycle into defrost mode, clearing frost from the coils and keeping performance steady.
The secret is installation. Units need to be placed on stands, well above snow lines, with proper drainage to prevent ice buildup. We also take care to position equipment where it’s sheltered from heavy snow drifts.
We’ve installed systems that continue running through snowstorms and cold snaps. With the right setup, freezing up simply isn’t a problem.
Local Success Stories: Heat Pumps in Northwest BC
We’ve seen firsthand how well cold-climate heat pumps perform here at home:
Terrace: A family swapped out their old gas furnace for a Moovair Heat+ system. Even during a cold snap of -20°C, their living room stayed a steady 21°C without relying on backup heat.
Kitimat: In a 1960s home, we retrofitted ductwork and installed a high-efficiency heat pump. Even on the chilliest nights, the system carried most of the load, with minimal help from auxiliary heating.
These aren’t exceptions—they’re becoming the norm for well-designed installations in northern BC
Why Heat Pumps Make Sense in Northern BC
Lower Heating Costs – With rising utility prices, homeowners are saving hundreds every year.
Rebate Programs – CleanBC and Northern BC top-up rebates make installations more affordable than ever.
Long-Term Value – Cold-climate heat pumps offer reliable comfort, year after year, with less maintenance than many traditional systems.
Energy Efficiency – More of the energy you pay for goes directly into heating your home instead of being wasted.
Tips for Choosing a Cold-Climate Heat Pump
Always start with a heat-loss calculation. It’s the only way to know what size system your home needs.
Select a model rated for -25°C to -30°C operation. Not all heat pumps are created equal.
Have an electrician verify your electrical capacity to convert to a heat pump.
Plan outdoor placement carefully. Stands, drainage, and snow clearance are critical for reliable performance.
Ask about ductwork. Adjustments to airflow can make a big difference in both efficiency and noise control.
The Bottom Line
Yes, cold-climate heat pumps work in Northwest BC. With the right equipment and installation, they provide consistent comfort, lower heating bills, and peace of mind during the harshest winters.
At Village Mechanical, we’ve helped families across Terrace, Kitimat, and the surrounding areas make the switch with confidence.
